Embodiment Construction

[0058] The following is a description of the embodiments, the specific embodiments of the present invention are described in further detail.

[0059] as Figures 1 through 8 As shown, the overall wheels of the railway wagon, including hub 1, spoke plate 2, spoke 3 and tread 4, spoke 2 is a curved structure, one end of spoke plate 2 is connected to hub 1, the other end of spoke plate 2 is connected to rim 3, and the rim 3 is provided with rim 14 and pedal 4 at one end away from spoke plate 2.

[0060] Axially upwards, the spoke-spoke transition zone is located on the outside of the hub-spoke transition zone. The angle between the outer contour line of the hub 1 outer diameter surface hub 11 and the outer hub surface of the wheel hub 8 is Φ1, Φ1≥98 °. The angle between the inner contour line of the hub 1 outer diameter surface of the hub 12 and the inner hub surface of the wheel hub 7 is Φ2, Φ2≥100 °. The angle between the rim inner diameter surface rim outer contour line 13 and the ...

Abstract

The invention discloses a lightweight heavy-load wheel set and a design method thereof, the wheel set comprises an axle and wheels arranged on the axle, and the axle is of a cylindrical structure; each end of the axle comprises an axle wheel seat area; the wheel comprises a hub, a radial plate and a rim, the radial plate is of a bent structure, one end of the radial plate is connected with the hub, the other end of the radial plate is connected with the rim, and a tread and a rim are arranged at the end, away from the radial plate, of the rim. The radial plate comprises a hub-radial plate transition area, a radial plate body and a rim-radial plate transition area. The wheel is arranged on the axle wheel seat area, and the rim-radial plate transition area is located on the outer side of the hub-radial plate transition area in the axial direction; the hub-spoke plate transition area is located between the hub and the spoke plate body, and the rim-spoke plate transition area is located between the rim and the spoke plate body. The wheel disk body is of a bent structure, and the wheel disk is connected with the rim and the hub through arcs. The unsprung weight of the bogie can be effectively reduced, wheel track abrasion is reduced, and the transportation efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of rail wheel technology, in particular to a lightweight heavy-duty wheelset and a design method thereof. Background [0002] The transport vehicles commonly used in industrial and mining enterprises are railway trucks for special purposes, and the general axle load can reach more than 40t. Among them, the working condition vehicle specially used for the transfer of molten iron in the iron smelter is a torpedo tanker, which has a total load of more than 600 tons, and the wheel set axle weight of the torpedo tanker can reach 50t, which belongs to the heavy-duty wheelset. [0003] Heavy-duty wheelsets are mainly composed of two wheels and an axle by means of interference fit. Among them, the axle is mainly composed of four parts: shaft journal, dust seat, wheel seat and shaft body; the wheel is mainly composed of three parts: hub, spoke plate and rim. The structure of the axle is mainly composed of the shaft end stru...
